【摘要】 Given a sorted linked list, delete all duplicates such that each element appear only once. For example, Given 1->1->2, return 1->2. Given 1->1->2->3->3, return 1-... Given a sorted linked list, delete all duplicates such that each element appear only once. For exampl...
Given a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. For example, Given1->2->3->3->4->4->5, return1->2->5. Given1->1->1->2->3, return2->3. 非经常规的解法。为去除头节点的特殊性,须要用到虚拟头结点技术。
链表(Linked List)相比数组(Array),物理存储上非连续、不支持O(1)时间按索引存取;但链表也有其优点,灵活的内存管理、允许在链表任意位置上插入和删除节点。单向链表结构一般如下: //Definition for singly-linked list. struct ListNode { int val; ListNode *next; ListNode(int x) : val(x), next(NULL) {...
Explanation: 2 appears twice in the linked list, so all 2's should be deleted. After deleting all 2's, we are left with [1,3]. 1. 2. 3. Example 2: Input: head = [2,1,1,2] Output: [] Explanation: 2 and 1 both appear twice. All the elements should be deleted. ...
